The SITRANS F M  MAG 5100 W  with its patented liners of hard rubber NBR or ebonite and EPDM is a sensor for all water applications such as ground water, drinking water, cooling water, waste water, sewage or sludge applications.  

In order to  have a complete flowmeter, please  combine it  with one of the following MAG transmitters:

 SITRANS F M MAG 5000: Cost efficient transmitter, accuracy of + 0.4 % of flow rate

SITRANS F M MAG 6000: Bus communication, batch function and accuracy of + 0.2 % of flow rate

SITRANS F M MAG 6000 I: Alu enclosure, Ex approvals, bus communication, batch function and accuracy of + 0.2 % of flow rate

The sensor can be combined with the energy calculator  SITRANS FUE950  

Application examples: Water abstraction, Water distribution network, Waste water and as custody transfer water meter or cooling meter.
